If you’ve been shopping for a new hair brush recently, you may have come across the term ‘ionic’.
Ionic hair tools have been a trend for a while now, so we thought we’d take the time to actually explain how they work, and why we think they’re more than just marketing hype.
We get to these root questions and more in this comprehensive breakdown.
How do ionic hair brushes work?
Let’s talk science. First things first, you should know that your hair is made up of positive and negative ions.
When you create friction by brushing your hair or towel-drying it, you strip your hair of negative ions. This upsets your hair’s natural state, causing frizz and static.
Fortunately, ionic hair tools such as brushes can reverse this effect. When you heat up an ionic hairbrush and brush your hair with it, you add negative ions back into your hair and restore its natural charge.
That ultimately means you get hair that's shinier, smoother, and less frizzy.
The benefits of using an ionic hair brush
By bonding the negative ions with your hair, an ionic hairbrush will cause your hair to look and feel smoother.
Helps to close the hair cuticle and locks in moisture.
They reduce drying time and therefore minimise damage.
When used with a heat protectant like the Kérastase Résistance Ciment Thermique 150ml an ionic hairbrush will help protect your hair over time.
